Introduction
In 1940, the U.S. Army Air Corps drew up a requirement for a radio-controlled target drone for training anti-aircraft artillery gunners. The first aircraft in a series of target drones was a modification of the Culver LFA Cadet which eventually led to the PQ-14 series used throughout World War II and beyond.

Design and development
Culver proposed a modification of its civilian Model LFA Cadet which the Army purchased as the PQ-8. The success of the PQ-8 led to the development of the “NRD”; a single PQ-8 was converted to the new configuration and tested by the USAAF as the XPQ-14. Larger and faster than the PQ-8, the PQ-14 also had retractable landing gear and fuselage, wings and tail components made of wood with stressed plywood skin.

This prototype was followed by YPQ-14A service test aircraft and 1,348 PQ-14A production models. Of the latter, 1,198 were transferred to the US Navy, which designated them as TD2C-1 with the decidedly unattractive name Turkey.

The YPQ-14B was a slightly heavier variant; a total of 25 were produced before production shifted to the PQ-14B. A total of 594 PQ-14Bs served as target drones for the USAAF. A single PQ-14B was converted to use an O-300-9 engine and designated XPQ-14C. After World War II, the Culver company developed the XPQ-15 from their Model V light aircraft. After only four were delivered the company went bankrupt in 1946.

Operational history
The XPQ-14 was first flown in 1942 and began to be received in training units shortly after. The aircraft was flown unmanned, controlled by radio, but was flown by a pilot for ferry flights, utililizing a rudimentary control panel installed for that purpose and using their parachutes as a seat. Docile and easy to fly, the aircraft was finished in a bright red target color scheme although operationally, a silver or red finish was applied. Without a pilot they were flown from a “mother ship” aircraft. The typical mother ship was a Beech C-45. Despite their short lifespan, the aircraft performed well and the Franklin engine was considered “trouble-free”.

Most of the Culver target aircraft were “blasted out of the sky” by Army anti-aircraft gunners but a dozen or more survived and were surplused after 1950. Flown as a recreational aircraft, their new owners found that the aircraft had a sprightly performance. One is preserved as a flying example at the Planes of Fame in Chino, California, another is part of the collection at the National Museum of the United States Air Force and a third N5526A, that flew to airshows throughout the 1970s holding the last airworthiness certificate is displayed at the Airpower Museum at Blakesburg, Iowa.
